ZJQ Submersible Sand Pump Manufacturer – Compact Solution for River Sand Dredging

Project Background

Recently, Taian OCEAN Pump Co., Ltd. received an inquiry from a customer in Xi’an who was looking for a compact, lightweight, and easy-to-operate sand suction pump for river sand extraction.

There is a small river near the customer’s site. The river depth is only about 1 meter, and the water is clean and shallow. However, a large amount of fine sand has accumulated at the bottom of the river.

Due to the increasing demand and shortage of local sand resources, the customer planned to extract the deposited river sand for commercial use.

Considering the shallow water depth, limited working space, and the customer’s requirement for convenient operation, OCEAN Pump engineers recommended the ZJQ submersible sand suction pump as the ideal solution.

What is ZJQ Submersible Sand Pump?

The ZJQ Submersible Sand Pump is a hydraulic pumping device that integrates the motor and pump into one unit and operates directly underwater.

Unlike traditional surface-mounted sand pumps, the ZJQ series can work completely submerged in the medium, eliminating the need for complicated installation platforms and additional protection systems.

The pump is specially designed for pumping liquids containing:

• Sand particles
• Gravel
• Coal slag
• Tailings
• Sludge
• Other abrasive solid materials

It is widely used in:

• Mining operations
• Metallurgical industries
• Thermal power plants
• River dredging
• Sand extraction projects
• Tailings treatment
• Industrial waste removal

Advantages of OCEAN Pump ZJQ Submersible Sand Pump

1. Direct Underwater Operation

The motor and pump are integrated into one compact unit.

Main advantages:

• No need for complex foundation construction
• Easy installation and operation
• Reduced equipment investment
• Suitable for narrow or difficult working environments

The pump can be directly lowered into water and start working immediately.

2. Built-in Agitation System for High Concentration Sand Pumping

Different from ordinary slurry pumps, the ZJQ submersible sand pump is equipped with an additional agitator impeller at the bottom of the pump.

During operation, the agitator:

• Breaks up settled sediment
• Creates turbulent flow
• Loosens compacted sand layers
• Improves suction efficiency
• Increases solid concentration during transportation

This unique design allows the pump to achieve high-concentration sand pumping without additional flushing equipment.

3. Strong Wear Resistance and Anti-Clogging Performance

The main wet-end components, including:

• Impeller
• Agitator
• Pump casing

are manufactured using high wear-resistant materials.

Benefits include:

• Excellent abrasion resistance
• Corrosion resistance
• Large solid passage capability
• Reduced blockage risk
• Longer service life

The pump is especially suitable for harsh conditions containing abrasive particles.

4. Safe and Quiet Underwater Operation

Because the complete unit works underwater:

• Low noise
• Low vibration
• No pollution
• Compact structure
• Better working environment

The pump can operate safely even in challenging field conditions.

Customized Pump Selection for River Sand Extraction

After understanding the customer’s working conditions, OCEAN Pump engineers recommended:

This model was selected because:

• Moderate weight for transportation
• Easy manual operation
• Wide flow passage
• Strong anti-blocking capability
• Suitable for fine sand extraction

The customer received detailed product information, operation videos, and technical recommendations before confirming the order.
